Actually let's wait a bit with this. For SM8550 we had an idea to move
interconnect to their own bindings file, because they will grow a bit
with allOf:if:then clauses.

Maybe SM8450 and QDU1000 should also go to their own files which will
describe all their interconnects (the virt and the ones requiring clocks)?

Apologies for bringing it late for your patches, but SM8550 is also
happening right now, so new things pop-up :)

Best regards,
